SHEAF SHO'CKER.

Application filed January v25, 1922. Serial N'o. 531,784.

T all whom it may concern.'

Be it known that I, OTTO FILMAN HAM- MILL, of the city of Calgary, in the Province of Alberta and Dominion of Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Sheaf Shockers, of which the following is a specification.

-This application is a continuation, in part, of my application, Serial No. 472,785 filed May 2e, 192i.

This invention relates to improvements in sheaf shockers, and the objects of the invention are to provide an effective device of this character which will receive the sheaves from the binder, form them into properly compressed and shaped shocks and deposit them in upright position on the ground.

More particular objects of the invention are to effect proper compression of the upper part of the shock and spreading of the lower part thereof during discharge in order that the shock when deposited may have a maximum amount of stability.

The invention relates to a type of shocker in which the sheaves are deposited into a shock forming member or basket and by this member formed into a shock and deposited on to the ground.

Further objects of the invention relate to an improvement in a shock forming member' to enable it to receive-the sheaves at one side and discharge them at the other, thereby avoiding the necessity of lifting the basket from the shock when placed.

Further objects still relate to the tripping and operating mechanism for the basket, the latter being thrown into operation by thev initial movement of the basket under gravity and designed to complete the operation of the basket and return it to normal position.

Further objects still are to essentially improve and simplify the construction of the device to better adapt the various parts to perform the functions required of them.

In its construction, the invention includes a shock forming member and basket formed in two co-operating parts mounted on tracks designed to cause the basket to open alternately on opposite sides to receive and discharge the sheaves in combination with a baseboard and spreading means, and power operating mechanism by which the various parts are operated in proper sequence, all as hereinafter more fully set forth and described in the accompanying specification and drawings.

In the drawings, like characters of lreference indicate corresponding parts in all the figures.

Referring to the drawings:

A indicates a shock forming member or basket carried on a suitable truck B and fed with sheaves by a suitable elevator C operating from the binder deck D. The truck B may be of any suitable or convenient design to support the working parts, that illustrated having side wheels 10 and a castor wheel 11, the truck carrying a suitable frame E of suitable shape and design to properly support the various operating parts.

The elevator C may be of any suitable or convenient design. I have illustrated a well known type comprising endless chains 12 carrying transversely extending and pivoted `forks 13 which are maintained in upright position; by means ot projections 14 which engage with flanges 15 on the side oit the elevator casing 16. (See Figure 19.)

The elevator is driven in arsuitable or convenient way. I have shown it driven by means of aA chain 17 leading from a y sprocket 18 on a countershatt 19 connected by a gearing 2O with a sprocket 21 driven by a chain 22 from a sprocket 23 on the sha lit. 24 of one of the wheels l0. lNhile the sheaves are passing up the elevator and discharging into the shock forming member they are guided by suitable guide rails 241 which extend parallel with the elevator and are supported on a. transverse member 25 of the frame, the latter being ot inverted U shape designed to yguide and cause discharge of the sheaves into substantially the centre of the shock forming member. The connection between the guide rails 241 and the transversely extending member 25 is constituted by a rod 27 (seeFigure 3), the outer end of which is connected by a bracket 28 to the side ot the elevator casing 16. The rod 27 is also provided with vertical lingers 26.

The shock forming member or basket C is formed with two semi-circular andV similar sections 30 each mounted at opposite sides on guide tracks F by which the movement of each section is controlled, the shape of the tracks being such as to cause the sections to close together, to turn downwardly and open rearwardly to compress and discharge the sheaves in the form of a shock as hereinafter explained. It will be seen that each .pair of tracks F comprises an upper rail 31 and a lower rail 32. The central portions ot' all the rails extend parallel with each other for a' distance, then the rails ot each pair diverge trom-those of the other pair at the rear as shown in Figure 3. They also curve upwardly, outwardly and backwardly at the forward end. (See Figures 1 and 2.) One rail of each pair also curves outwardly at the forward end to cause expansion ot the top as well as opening the basket to receive the sheaves. On the discharge, the contraction or movement of the top portions towards each other will compress the top ot' the sheaves.

The connection between each section ot the basket and its respective track may be of any convenient character which will allow tree and easy motion ot the section on the track, and is preferably formed with rollers or balls to reduce any unnecessary friction. In the forni of connection which I have shown, a bracket 33 is provided connected to each section 30 and designed to lit within a flange 34 formed around a rectangular trame 35 to which it is adjustably connected, as by bolts 36 extending through corresponding perforations in the bracket and frame, a series oit periorations being provided in each to provide ior adjustment between them to correspond with dili'erent lengths of grain. The frame 35 has sockets 37 secured to the side thereof which form bearings for pivot pins 38 retained in the sockets by means of threaded extensions 39 extendingthrough the ends of the sockets and having retaining nuts 40 thereon. lThe outer end ot each pin 39 is formed with diverging arms 41 and 42 which carry itriction` rollers 43 adapted to run on the upper rail 31, a third friction roller being mounted at the end of the pin 38 centrally between the arms 41 and 42.

The lower rail is engaged by a plurality oit corresponding rollers 44 mounted in arms 45 on the rod 46 which is mounted in bearings 47 and 48 on the fname 35.

Each of the sections 30 is curved, being partially conica-l `in shape and is formed with spaced forks 50' having the ends at both sides designed to overlapthe opposite section according to which side of the basket is open. The lower sides oi the sections are also formed with overlapping projections 51 designed to secure registration of the sections when brought together and hold them in proper alignment when separated slightly.

The sections oie the basket tend to move by gravity on. the tracks to discharge. position and their motion in this direction is normally prevented by means ot a pivoted trip 52 pivoted on a member 25 and normally spring held in engaged position by a spring 53, being released by means of a cord 54 which extends over a suitable pulley or pulleys 55 to a position adjacent to the drivers sea-t. rlhe trip is formed with a laterally turned end which normally engages a stop 56 on the side ot a trip gear wheel 57 (see Figures 9, 10 and 11) mounted on a stub shaft 58 and meshing with a. pinion 59 carried on a countersha'l't 6() which countershaft is provided with spirally curved pulleys 61 having cables 52 which lead over suitable pulleys 63 to the sides of the sections of the shock forming basket A. Springs 62a may be interposed between the. cables and sections 30 to absorb shock. It will be seen that when the trip is in normal position, the gear 57 ca-n not move, which will prevent turning of the pinion 59 and the sha-ft 60 which through the pulley 61 and cable 62 will retain vthe sections in their raised and expanded position.

Upon release of the trip 52, the sections 30 will commence to move downwardly on the tracks under gravity,'and infY so doing they are designed to throw into opera-tion the power operating means presently to be described.

The trip gear 57 carries cam plates 64 and 65, the cam plate 64 eXtending'arcund three-quarters of the periphery of the gear Yof the sections 30 acting through the cables 62. The turned end 66 on the cam 64 is designed to enga-ge a. roller 67 on a slidably mounted operating rod 68 and move the same in the direction indicated by the arrow in Figure 12. The outer end of the rod 68 is connected to a centrally fulcruined clutch control lever 69 pivoted to a bracket 70 and connected to a clutch block 71 adapted to rotate with the shaft 60 but slidably mounted thereon the said block having pins 72 on one side designed to enter suitable orifices in the hub of a bevel gear 73 during `discharge of the shock forming basket, and

formed on the opposite side with pins 74 designed to enter suitable recesses in a bevel gear 75 on the return movement of the basket. In neutral position, the pins 72 and 74 will be free from either gear. The gears are caused to rotate in reverse direction to each other by a connecting gear 76 suitably mounted on the bracket 77 connected to the member 25. The gear 73 is connected to and driven continuously from a sprocket 78 y which is connected by a chain 79 with a corresponding sprocket 80 carried by and turning with one of the wheels 10. It will be seen that when the rod 68 is moved outwardly by engagement of the portion 66 of drums 82 provided 0n the shaft 60. It will be seen that the tightening of these cables 801 will draw the sections of the basket on the tracks to their rearmost or dischargi vthe bracket 70, will pass beyond the end'of the portion 64. Then the roller passes beyond the end of the portion 64 it will permit the rod 68 to be moved into reversed position under action of the spring 86, whereupon the pins 74 will engage with' the gear 75 and the shaft 64 will bev driven in the reverse direction. The reverse operation of the shaft will, through the cable 62, draw the basket back to its normal position during which movement the ro'ller 68 will pass on the opposite side of the cam 64 to that on which it previously moved, and will finally reach the curved portion 87 on the cam 65. This curved portion will then move the roller 67 back to its normal position, the said roller springing under the end 66 on the cam 64, which end is split atV 88 to render it suiliciently resilient to permit. of the passage of the roller beneath it,'as in! dicated in dotted lines in Figure 9. During this movement, the clutch control lever 69 willbe moved bythe rod 68 to neutral position causingk the reverse movement of the shaft 60 to cease, at which time the trip rod 52 will have engaged with the stop block 56 retaining the parts in their normal position.

During formation of the shock, the of the sheaf are supported by a pivotally mounted baseboard Gr which is pivoted at its lower extremity to short links 90 pivoted to depending brackets 91 on the bottom member 92 0f the frame. These links permit the baseboard to be swung from its normal position shown in full lines in Figure l to its lower position shown in dotted lines in Figure l, its movement being also controlled by means of a link 93 which extends from the frame 92 to the side of the baseboard. The movement of the baseboard is controlled by a cable 94 which extends over the pulley 63 and is connected to the cable 62 by means of a plate 95 through which the cable 62 extends, but which is adapted to" be engaged by a knot or stop block 96 on the cable 62 butts (see Figures 16 andl7). The baseboard Gr is caused by gravity to move to lowermost position and is arrested by the plate 95 engaging the stop block 96. During discharge, the movement of the cable 62 will permit the plate 95 to move and the cableV 94 to lower the baseboard a given amount,

Y end 112 during movement of the cable 62 in this movement being finally arrested byn means of a stop bracket 97 on the frame which engages the plate 95, the bracket being provided with an eye 98 which permits the knot 96 to pass through it but which arrests the movement of the plate 95. YA. spring 99 is interposed between the end of the cables 94( and the baseboard in order to lessen the jar and give a resilient support to the baseboard in normal position. rllhis resilient support is such that the baseboard when the shock forming member is empty is, held in the position shown in full lines in Figure 1. lt will be maintained in this position during the discharge into the shock forming member of the first few sheaves. As the sheaves accumulate in the shock forming member, the spring will permit the baseboard to give a little and to move as indicated in dotted lines in Figure 1 thereby giving greater accommodation for the base of the sheaves, thereby avoiding while the first few sheaves are collecting` the open` ing of any wide space between the members 30 and the baseboard.

In order to cause spreading of a portion of the butts of the sheaves during discharge of the shock, diverging shoulders 100 and 101 are formed on the baseboard G. To maintain or continue this spreading action, diverging forks 102are provided at the end of the shoulders and project from the baseboard to the ground. (See Figures 1 and 2.)

To prevent discharging of the sheaves from the binder into the shock forming member while the latter is discharging, a pivoted fork 103 is provided, mounted above the shock forming member on suitable brackets 104 designed normally to be free to tilt. downwardly under the weight of each sheaf, being returned to normal position by the weight of an arm 105, the downward movement of which is limited by a detent bracket 106. To prevent downward swinging of the forks 103 and corres 30nd-r ing upward swinging of the arm 105 during discharge of the shock forming member, l provide a pivoted detent lever 107 pivoted to a suitable bracket 108. The detent lever is formed with a hook-shaped end 109 designed to be brought across the end of the arm 105. The detent .lever 10T is operated by means of a pivoted operating' lever 110 pivoted to the member 111 of the frame. Said detent lever is formed with a forked end 112 designed to be engaged by the plate 95 on the cable 62. Then the plate is removed from engagement with the forked the discharge of the shock forming member, the lever 110 will move under action of the spring 114 and operate the detent lever 10T, as already explained. 1t will be seen, therefore, that until the plate 95 is returned to normal position, which will take place when the shock forming member itself is returned to normal position any tilting of the fork 103 is prevented by engagement of the detent lever 107 with the projecting end of the arm 105.

Suitable provision may be made for the adjustment of the height of the shock formv ing mechanism from the ground to suit varying crop conditions. rlhe means which `I have shown to accomplish this purpose the Aconveyor C andL lifted, finally passing on to the fork 103 which permits them to drop one by one into the shock forming member, being guided finally by the fingers 26. The upper sides of the sections 80 of the shock forming member will be open and expanded at the top as shown in full lines in Figures 2 and 3. f

lt will be seen that owingv to the tapered form and curved form of the sections, the sheaves will be caused to arrange themselves in a proper shock at the same-time the machine is moving over the ground and the baseboard being resiliently supported will permit a slight shaking movement against the resilience of the spring, which will further cause proper formation of the shock. lhen the driver has ascertained that there is a sufficient number of sheaves in the shock forming member to form a proper shock, he pulls the cable 541 to release the trip 52 which through the mechanism already described, will permit the sections of the shock forming member first to move under their own weight and then to be moved by the power' mechanism to discharge position. The movement of the upper part of the shock forming members towards each other will compress the upper part of the sheaves at the beginning of the operation. At the same time, the shock forming member will be moved from a position slightly inclined to the horizontal to a substantially vert-ical position. The variation in the speed of the shock forming member with respect to the ground will cause the butts of the sheaves to be spread slightly upon the ground. The butts of the remaining sheaves will in the meantime have been spread by engagement with the flanges 100 and 101 of the baseboard. In this way7 an effective spreading of the butts of the shock is provided for.

The shock forming members continuing to move rearwardly on the rails 3l and 32 will finally open. at their` rearward or stubbleward side, moving to the position shown in dotted lines in Figure 3 and leaving the shock well set up in a stubbleward direction while the sections of the shock forming mechanism are returning to normal position by the mechanism the operation of which has already been described.

It may be pointed out that after the shock is deposited on the ground, the pressure of the shock forming member on the upper part of the sheaves will by reason of its conical shape compress the same together into a rm and stable shock, after which the stubbleward side of the basket will open to permit the basket to be withdrawn and returned to its normal position in which it will be raised and opened ready to receive the new sheaves.

It will be seen that the adjustment between the brackets 33 and the frame 35 enables the relative position of the sections 30 to be adjusted andby this means a variation may be made in the extent of the compression at the top of the shock. lt will also be seen that the adjustment at this point will cause the sections to beopened to a greater or less extent at the top of the upward movement. f

It will be seen that by reason of the fact that the worm pulleys 61 and 82 are spirally formed a variation takes place in the speed at which the cables are paid out or dra-wn in and this variation in speed is taken advantage of in order to cause the sections 30 of the shock forming member to move at different speeds during their discharge. The initial movement of the sheaf forming basket from open and spread position takes place at a minimum speed. The speed then greatly increases until, when the first part of the shock drops onto the ground, the sheaf forming basket is moving slower than the movement of the entire machine over the ground. The variation in speed of the shock forming basket with respect to the ground will then cause the butt of the sheaf to be spread slightly upon the ground. Byl the time the remainder of the shock is dropped onrthe ground, the shock forming basket will remain temporarily with the shock, pressing it to form on'the ground, and finally leaving it in such position. The balance of the movement of the sections is then completed, the final movement taking place at reduced speed. It will be obviousthat the speed of any part of the movement may be regulated by the diameter of the groove on the controlling pulley for that part of its movement.
